Detailed Description

template<typename R, typename T>
class gtsam::FunctorizedFactor< R, T >

Factor which evaluates provided unary functor and uses the result to compute error with respect to the provided measurement.

Template parameters are

Parameters

R	The return type of the functor after evaluation.
T	The argument type for the functor.

Example: Key key = Symbol('X', 0); auto model = noiseModel::Isotropic::Sigma(9, 1);

/// Functor that takes a matrix and multiplies every element by m class MultiplyFunctor { double m_; ///< simple multiplier public: MultiplyFunctor(double m) : m_(m) {} Matrix operator()(const Matrix &X, OptionalJacobian<-1, -1> H = {}) const { if (H) *H = m_ * Matrix::Identity(X.rows()*X.cols(), X.rows()*X.cols()); return m_ * X; } };

Matrix measurement = Matrix::Identity(3, 3); double multiplier = 2.0;

FunctorizedFactor<Matrix, Matrix> factor(keyX, measurement, model, MultiplyFunctor(multiplier));
